I'd like to delete or to archive a picture which is in the RAM. Is that possible in asm ? (I know a lot of things is possible in asm, but we never know).
I know that with RST 10h (I don't understand why we're not allowed to write RST $10) we can determinate whether the picture is in the RAM, or even if it's archived, but can we change this status ? Can we delete a picture ?
(after that, I'll delete the kernel32.ddl which is on my TI :-P Don't laugh, there is a OS which can be damaged ;)

Look up "DelVar" in the systemroutines document. Quite simply, follow up an RST 10h immediatly with a bcal(DelVar), and poof! The variable goes byebye.

Speaking of the OS, I believe that messing with what's stored at ROM-page 0 is really, really bad.

For sure ! But don't be affraid : first of all, I'm not good enough in asm to do that, and then, I allways test my programs on my own TI, and I don't want to detroy it neither Smile
Now that I know how to delete a variable (how easy it is with DelVar !), do you know how to archive a varible ?
It is possible with a BASIC function, so why not in assembly Wink

I've found !

I searched "Arc" in the asmTI83p.inc and I found a rom_call named Arc_Unarc.
Owever, as I didn't found any documentation on how to use this function.

So I've tested it on my calc and it works perfectly, and easyly !!
In fact, as its name says it, it works as Del_Var (I mean, its input are the utputs of RST 10h) and when you use it on a archived var, it disarchive it and vice versa

cool
When my program is finished (soon), I'll tell you what it is (nothing especially difficult to do)

[font="Arial"]Here it is !
I've put it on my other FTP because the first one is "dead" :-(

So what is it ? Well, it is simply a viewer for TI-83+ (as ACD-SEE for PCs) !
In fact, this is the second version of this program (the first moved the pictures from the top to the bottom of the screen ; it was pretty but it was too long for a viewer).

What's more, I think someone here is doing an OS (or a shell), yeah, that's it : WallsXP. So I though he could use this if he wants to include a viewer Wink What's more, there isn't any advertising and all the strings are in English ! Laughing


Now that's this program is finished, I'm gonna wait 'til it is available on ticalc.org and Im gonna continue my website on nwn Wink

well, it sounds pretty nice, but when i click the link, it comes up with an empty .zip Neutral ... now, i want to know, does it display the small versions of the pics, or the big versions? (small versions, as in, every other pixel or so....)

Try doing "load target to...", instead of "open".
The zip contains 4 files : the source, the .8xp file, the readme and the include file.


It displays large pictures.

ah, i took a look, and it looks alright, but i think i will go off an idea from cirrus, and make it display a few mini pictures... and then u choose which one u want and what not...

actually, i tried to do my own pic files type thing... it didnt work so well... what i did, is try and make a prog that just had a pic in it... and when u open it in WALLSxp, it would display it... lets just suficeth it to say that if there wasnt an image on ur drive, then it would have disatrous results Neutral
